We are faced with situations at one time or another that make us angry. This is a part of human nature… we have feelings and emotions. However it is not healthy to hold on to anger, for your own healing and peace of mind you have to let it go
Ephesians Chapter 4 V 26&27 says “Don’t sin by letting anger control you. Don’t let the sun go down while you are still angry, for anger gives a foothold to the devil.”
